Identity code generation method

Abstract

The invention discloses an identity code generation method. The identity code sequentially comprises a product code, a data code, a random code and a check code; the method comprises the following steps of: (1) pre-generating a random mapping relation between the product code and a product barcode; (2) pre-generating the random mapping relation between the data code and the date of every day; (3) pre-generating the data of the random code; (4) acquiring the corresponding product code from the mapping relation according to the product barcode; (5) acquiring the corresponding date code; (6) acquiring the random code and recording the beginning, the destination, the number of the applied code and the product ID; (7) encoding and generating a new product code and encoding the product code; (8) encoding and generating a new date code; (9) jointing the code into a temporary identity code; (10) calculating one check code; (11) jointing the identity code obtained from the step (9) and the check code obtained from the step (10) into a final required identity code.

Description

technical field [0001] The present invention relates to the field of automatic identification of product identities, and more specifically relates to the identification of barcodes, two-dimensional codes and RFIDs. More specifically, the present invention discloses a method for generating identity codes, which can generate a random Anti-counterfeit identity codes that are irregular, but contain certain logic and can integrate product barcode information, have a long validity period and huge capacity, to achieve the purpose of marking the unique identity of each item in the world. Background technique [0002] At present, there are some product anti-counterfeiting identification labels on the market, which are used for authenticity identification of products when consumers purchase products. Most of the anti-counterfeiting identification marks on these product anti-counterfeiting identification labels are in digital form, and these numbers are often short in number, which ca...

Problems solved by technology

The main problem brought about by digital anti-counterfeiting is the inconvenience of inquiry. Consumers need to enter the digital anti-counterfeiting ID code into the terminal query device (SMS, portal website) one by one. Manual input brings inconvenience to consumers. It also creates the possibility of input errors

At the same time, due to the use of digital anti-counterfeiting identity codes, industrial-grade collection equipment (such as POS machines, PDAs) in the circulation link will not be able to collect their identity information. As a result, the circulation path of this product cannot be recorded, and deeper anti-counterfeiting traceability

[0006] 2) Small capacity

However, if the generation algorithm of the anti-counterfeiting identification code that is not logically segmented is adopted, it will bring huge overhead in physical storage and data query when massive data is accessed, and it is impossible to obtain
